Referring to fig. 1 to 4, the present embodiment provides a liquid cooling system. The present embodiment is an improvement on the technical basis of the first embodiment described above, and is different from the first embodiment described above in that:

A liquid level sensing assembly 110 is disposed in the first liquid storage tank 100, and the liquid level sensing assembly 110 is used for measuring the liquid level in the first liquid storage tank 100.

The liquid level sensor is electrically connected with the first sensor, the second sensor and the controller respectively.

The liquid cooling system further comprises a second liquid storage tank 700, and the second liquid storage tank 700 is connected with the second interface of the first liquid storage tank 100.

The second tank 700 is capable of replenishing the first tank 100 with the cooling liquid when the liquid level in the first tank 100 is below the first liquid level; when the liquid level of the first liquid storage tank 100 is higher than the second liquid level, the first liquid storage tank 100 can discharge the cooling liquid to the second liquid storage tank 700.

The height of the first interface and the height of the second interface are lower than the height of the first liquid level.

When the liquid level in the first tank 100 is lower than the first liquid level, the controller controls the hydraulic pump 710 to be operated to ensure that a sufficient amount of the cooling liquid is injected into the cooler 800.

In the process of filling, the hydraulic pressure of the cooling liquid is high, so that when part of the cooling liquid flows back into the first liquid storage tank 100 through the first overflow valve 500 and the second overflow valve 510, the controller controls the second liquid discharge valve 720 to open, so that the first liquid storage tank 100 can fill the second liquid storage tank 700 with redundant cooling liquid.

When the cooler 800 drains the liquid into the first liquid storage tank 100 through the first drain valve 600, if the liquid level in the first liquid storage tank 100 is higher than the second liquid level, the controller controls the second drain valve 720 to open, so that the first liquid storage tank 100 may also inject the excess cooling liquid into the second liquid storage tank 700.
